The short answer
Yes, SwiftAir repairs air conditioners, heat pumps, furnaces, and ducts in southern San Mateo County communities from Redwood City and Menlo Park to Woodside and La Honda. We diagnose first and explain your choices. Bay Area Air District rules never force you to replace working equipment.
SwiftAir Conditioning Repair travels from our San Jose base to homes across southern San Mateo County, about 25 miles up the Peninsula. We repair central air conditioners, heat pumps, furnaces, and ductwork in East Palo Alto, Menlo Park, Atherton, North Fair Oaks, Portola Valley, Redwood City, Woodside, La Honda, and Emerald Lake Hills. On every visit, we find the actual cause of the problem, explain it in plain terms, and lay out your options before any work starts.
What We Repair
Most calls we get fall into a few common categories. A system that runs but doesn't cool or heat well usually needs a different fix than one that won't start at all, so we test before we recommend anything.
- Air conditioners that blow warm air, freeze up, or short-cycle
- Heat pumps that struggle in heating or cooling mode
- Gas furnaces that won't ignite, shut off early, or make new noises
- Thermostat, wiring, and control board faults
- Leaky, crushed, or disconnected ductwork that leaves rooms uneven
Homes and Weather on This Side of the Peninsula
Conditions change a lot within a short drive here. Bayside neighborhoods in Redwood City, East Palo Alto, and North Fair Oaks sit on flat ground, while Emerald Lake Hills, Woodside, Portola Valley, and La Honda are spread across hills with longer driveways, tighter equipment spaces, and older systems tucked into crawlspaces or attics.
Like the Santa Clara Valley we work in every day, the area has dry summers and mild, damp winters. Many homes rely on heating more than cooling, so a furnace or heat pump that falters in winter is often the more urgent repair.
Repair or Replace? What the Air District Rules Mean
San Mateo County is covered by the Bay Area Air District. Its appliance rules do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced.
Under Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date. If your furnace is aging, that timeline is worth weighing when you decide whether a repair makes sense. For water heaters, the Rule 9-6 date was set for 2027, but the Board is considering amendments in November 2026 that could delay it, so check the current rule before planning a replacement.
Incentives and Tax Credits
The federal 25C tax credit covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date. Homeowners can still check BayREN and their local clean energy provider for heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before quoting it.
